中文摘要：
本文用涂Ⅳ黏度计测定不同种类及不同添加量的阳离子和阴离子对1．0％CMC（w：w）溶液黏度的影响。结果表明：无论一价阴离子还是二价阴离子，Ca2＋和Mg2＋二价阳离子盐均能提高CMC溶液的黏度，尤其是Ca2＋的效果更加明显，CaCl2和CaSO4可以分别将CMC溶液的黏度最大提高47．0％和48．1％。而对一价阳离子Na＋盐而言，阴离子的作用就更为重要，NaCl使得CMC溶液的黏度降低，而Na2SO4也可在一定添加量内使CMC溶液的黏度提高。
英文摘要：
In this paper, influences of different ions with different quantities on viscosities of 1.0% CMC aqueous solutions were investigated by coating - Ⅳ - viscometer. The results showed that the viscosities of CMC aqueous so- lutions could be raised by adding salts of both Ca2＋ and Mg2 ＋, no matter anions were Cl - or SO024 ＋ , especially, the influence of Ca2＋ was more significant, e. g. , the viscosities of CMC aqueous solutions were increased maximally 47.0% and 48.1% by adding CaCl2 and CaSO4, respectively. Anions in sodium salts played more important roles in affecting the viscosities of CMC aqueous solutions, e. g. , adding NaCl into the solution made the viscosity of the solution decrease, but adding Na2SO4 made the viscosity of the solution increase at some additive concentration.
